please help - I am trying to find replacement runners for the drawers in my elderly dad's kitchen (which are now dropping and wobbly) and trying to find out how to fix them! The existing ones are metal slides with ball bearing cages which fit in a groove along the sides of the drawer box. Have tried to do it using standard type of runner from B&Q (the one with a little wheel) but these aren't right - even though they fit in the groove the drawer assembly is then too wide to fit in the cabinet. Can't find these other type on the internet (except USA sites) so don't know where to get them from. Any ideas? And if I can get them are they difficult to fix? Any advice would be much appreciated - especially as dad would like to avoid the expense of having to buy new drawer boxes/ drawer cabinets.
